caterpillar fungus

Quality is determined by the ratio of the larva body to the stroma (mushroom sprout). Premium grade Cordyceps should have a plump, bright golden-yellow to yellowish-brown body and a short stroma (usually not exceeding the body length). Look for clear transverse stripes (20-30 rings) and four pairs of distinct legs in the middle of the body. The interior should be white and crisp when broken, with a characteristic fishy and mushroom-like aroma.

In B2B trade, Cordyceps is primarily graded by count per kilogram. Top-tier 'King' grades range from 2,000 to 2,200 pieces per kg, while mid-range grades are around 3,000 to 4,000 pieces per kg. Ensure the moisture content is strictly below 12% to prevent mold and weight fraud. Buyers should also specify the allowable percentage of broken pieces (usually <3-5%) and ensure no metal wires or heavy metal powders have been inserted to artificially increase weight.

As a high-value biological product, it must comply with CITES (Convention on International Trade in Endangered Species) regulations in certain jurisdictions. Essential documents include a Phytosanitary Certificate, Certificate of Origin, and Health Certificate. For the US market, FDA registration is required, while the EU requires compliance with heavy metal limits (Lead, Cadmium, Mercury) and pesticide residue testing according to EC regulations.

Caterpillar Fungus is mainly sourced for pharmaceutical manufacturing (extracts/capsules), high-end health supplement brands, and luxury gift retail. Functional requirements focus on the concentration of active compounds: Cordycepin, Adenosine, and Polysaccharides. Buyers should request a High-Performance Liquid Chromatography (HPLC) test report to verify these active ingredient levels before finalizing a contract.

The highest risk is adulteration or weight tampering. Some suppliers may insert lead wires or soak the fungus in heavy metal salts to increase weight. To mitigate this, always use third-party inspection services (like SGS or Intertek) to conduct X-ray scanning and chemical analysis. Additionally, ensure the transaction is protected by Trade Terms on Made-in-China.com to secure your payment until quality is verified.

Prices for Cordyceps fluctuate based on the harvest season (May-July). It is advisable to lock in prices via annual framework agreements during the harvest peak. Negotiate for staggered shipments to maintain freshness. Demand vacuum-sealed packaging with desiccant and specify Incoterms 2020 (e.g., CIF or DAP) to ensure the supplier handles the complex export documentation for biological products.

Due to its high value and fragility, Air Freight is the only recommended method. The product must be packed in shock-proof, moisture-proof containers. Use temperature-controlled shipping (1-5°C) if the transit time exceeds 3 days to prevent oxidation. Ensure the cargo is fully insured for 110% of the invoice value, specifically covering 'all risks' including theft and spoilage.

Prioritize Audited Suppliers on Made-in-China.com who have undergone on-site factory/warehouse inspections. Check if the supplier has a Business License specifically allowing the trade of medicinal herbs. Request a video call to inspect the current stock and ask for the batch number tracking records to ensure the product is legally harvested and not aged stock from previous years.
